TRUCK.

SPECIFICATION forming part of Letters Patent No. 284,586, datedseptember 11, 138e.

Application filed June 18, 1883. e(Nonimlel.) I i l To all whom it mayconcern.;

Be it known that I, FRANKLIN F. ADAT/rs, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Trucks; and I do herebydeclare the following to be a full, clear, and eXact description of theinventipn, such as will enable others pertains to make and use the same.

This invention consists in providing certain new and useful improvementsin trucks for movingboxes, bales, barrels, Ste., as will hereinafterfully appear.

The class or style of truck to which this invention relates is such asare vmade low, with small rollers, and have no handles, and are adaptedto be easily placed under the article to be moved by rolling the articleoverl upon them, or raising` the article a little way up and sliding thetruck under it. In trucks of this class difficulty is experienced inguiding them when heavily loaded or when under a large box or bale,asthe rollers or wheels are not adapted to permit the turning of curvesas where they are mounted on axles which are pivoted. This difficulty Iovercome by the construction shown. which is as follows:

The truck is provided with five wheels, one in each corner and one inthe center, C C C C and D, and the one inl the center, D, is either 'ofgreater diameter than the others, or else has its bearing so placed 'asto bring its tread lower than the others. This arrangement causes thetruck to always run on only three of its five rollers or wheels-namely,the

central one, D, and two others; and it makes it easy for theoperator topoise the load on the central wheel and swing it around on that wheel,as on a pivot, and head the truck in any direction desired. The centralwheel should have a face of sufficient width to pre vent it marring thefloor, it being kept in mind that the weight, which is divided betweenthe two corner wheels C, is carried wholly by the central wheel attimes, and so should properly have a wider face; but as this wheel isused as 'a pivot, it is better not skilled in the art to which it ap-`to make the face any wider than necessary to prevent denting the floor.If the face of this 5o wheel D were beveled each way from the middle, itwould perhaps serve better as a pivot; but it would dent the floorbadly, and, be sides, it would require more care to guide the truck in adirect line than it would if the face of this wheel were as shown in thedrawings.

From the foregoing the principle of construction will be understood.

The details of construction are shown in the drawings, and are asfollows:

Figure l shows the truck in section on the line :c av in Fig. 2.' Fig. 2is a plan view of the under side of the truck. 1

I am aware of the construction of truck shown in PatentNo. 113,263, ofApril 4,1871,to John S. Cochran; and I do not claim as my inventionanything therein shown. In fact, my device is an improvement on saidconstruc- 8o tion, for by using only one wheel in the center of thetruck, in. place of two in the middle, the center of motion when turningis in the cen:

` ter of the truck, while in the othercase it must e on one side or theother, and in that case Amuch more space is required for turning than bymy construction.
